My father in law bought one last year. I couldn't get over how much available power it compared to my 5.4. It just seems to keep pulling. It also amazes me how much quieter it was over my Ford that's only 4 years old. If you buy one I would Fab a grill to cover the inter coolers since they are low and his has already taken some major hits from road debris. With that said is does say something in the warranty about putting anything in front of the inter coolers
